ECE 124d/256c Homework 5 Due: Wed Feb 10, 2010 Reading: DSE Chapter 4 1. Design a schematic and stick layout for the following cmos complex gates: a. f= ab+ac+ad+bc+bd+cd where arrival order is: a, b, c, d b. f=ad+ace+be+dcb where arrival is b, (a,c,e), and finally d. (note: static gate can be done in 10 transistors). c. Size the transistors for the circuits above so that rise and fall times are roughly equal, with the smallest transistor having an assumed relative size of 1. (Here you may assume that n-channel has

Calculate the proper CMOS driver size to source terminate a center driven 90 ohm transmission line with open terminations at its ends, using 1.8V 180nm technology. Show that the line is indeed terminated, despite being driven from the center, by superposing the reflections and transmissions at the center. DSE p. 216 Problems 4-2, 4-3, 4-5 2nS 90 Ω...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
